ORIENTED, HALOGEN-FREE, FLAME RETARDANT THERMOPLASTIC YARNS AND TEXTILE STRUCTURES MADE THEREFROM

摘要

An oriented, halogen-free flame retardant thermoplastic filament or yarn having physical properties, in particular tensile strength and elongation, that are similar to (or at least approach) those obtained from comparable filaments or yarns which do not provide any, or only limited, flame retardancy properties, as well as woven or braided components made from such yarns is provided. The yarns are made from a polymer blend of a first polymeric component that is a PET polyester having an organic phosphorus compound backbone with an Intrinsic Viscosity of at least 0.95, and a second component that is a polyester flame retardant concentrate based on an organic phosphonated ester which is combined with a polyester.
